Shilling works if they bid you up without going over your bid and then staying where they are.
I think what may have happened is that the seller had multiple accounts and that they simply used one to find his max and had another bid right under it, thus getting all they could out of him.
Just re-read original post, I didn't know it is possible to retract a single winning bid but keep your bid that is just under who is winning so they pay more. weird.
